It still utterly baffles me how Lyn manages to get her ponytail that high, let alone that far away from her head. That being said, her ponytail is really out there, mate. Also, random shaded spot on the spaulder. People forget to remove that from Fiora. The hair tie is kinda choppy, too.

No ideas for the swordy fellow. I'd just twiddle with some custom palettes.

Ooh I like that ponytail. But that trim on her collar doesn't look like it aligns with the rest of her body and I suggest bumping it to the right (our right).

As for the thief the hair doesn't look right. I think that if it's going to fall straight down then maybe have it come in front of that collar thingy. If it's going behind her back then I think you should angle it backward some more. (Or at least angle that bit coming over on the left, though the part on the right doesn't seem right heehee either)
